Lamination Stack Height at 65% stacking line efficiency: a worked example

Suppose stacking line efficiency falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Lamination stack height throughput measures how many laminated cores a stacking line actually builds per hour once real-world losses are factored in.

The inputs for this scenario

  • Cores stacked per shift: 1,200 units (held at the documented default)
  • Stacking runtime: 8 hr (held at the documented default)
  • Stacking line efficiency: 65 % (the input this scenario stresses; the baseline uses 90)

Working through the calculation

  • The calculation starts from the formula this tool documents: Raw lamination stack height = completed output รท runtime.
  • Effective throughput works out to 97.5 units at these inputs, and this is the headline figure for the scenario.
  • Raw throughput works out to 150 units at these inputs.
  • Efficiency works out to 65 % at these inputs.
  • Runtime works out to 8 hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where stacking line efficiency sits at 90% and the headline result is 135 units, this scenario comes in 27.78% below the baseline at 97.5 units.
  • It divides completed cores by runtime to get raw stacking throughput, then multiplies by line efficiency to get the effective cores-per-hour you can actually plan around. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Effective throughput: 97.5 units (headline result)
  • Raw throughput: 150 units
  • Efficiency: 65 %
  • Runtime: 8 hr
